brown. This appearance is very different from that in any- 

 other Lecanium I have seen. Margin with extremely small, 

 but moderately stout spines, fairly numerous. Term not 

 tesselate, but crowded with very large gland pits, which by 

 transmitted light appear dark brown on a light brown ground. 



Hab : — Trinidad, West Indies, in a nest of the ant 

 Cremastogastcr brevisjnnosa, Mayr var., sent by Mr. Urich, 

 •September, 1893. 



I was not able to study ibis species at the time it was 

 received, and until I made a careful examination of it recently, 

 I did not realize its interesting character. It is the first Lecanium 

 known to live in ants' nests, and is, besides, a very peculiar 

 form, perhaps subgenerically distinct from the rest of the genus. 

 Its shape and appearance somewhat recalls L. begonice Douglas, 

 but it is widely different from that in important characters. It 

 is also apparently the first Coccid found in the nest of any 

 Cremastogaster, the species of that genus being, according to my 

 experience, arboreal. 



[Since the above was written the species was found in 

 Brazil at Sao Paulo by Dr. von Ihering].
